SbVec2b(3)

💖 SbVec2b 💖

okay so bestie, welcome to the SbVec2b page from the Library Functions Manual — yes it's a manpage, yes it's giving vintage terminal chic, but we're gonna make it cute AND accurate, because knowing your vector classes is main character energy. 🎀

✨ NAME ✨

SbVec2b — a vector class for containing two byte integers. that's it, that's the whole vibe: two little bytes, vibing together, forever. 🦋

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull it in:

#include <Inventor/SbVec2b.h>

🫶 Public Member Functions 🫶

the constructors, aka the many ways to birth a SbVec2b:

• SbVec2b(const int8_t v[2]) — build it from an array of two int8_ts.
• SbVec2b(int8_t x, int8_t y) — build it from two separate int8_t values, one for each axis, slay.
• SbVec2b(const SbVec2ub &v) — convert from an SbVec2ub.
• SbVec2b(const SbVec2s &v) — convert from an SbVec2s.
• SbVec2b(const SbVec2i32 &v) — convert from an SbVec2i32.
• SbVec2b(const SbVec2f &v) — convert from an SbVec2f.
• SbVec2b(const SbVec2d &v) — convert from an SbVec2d.

the setValue squad — same conversions, but as a glow-up in place, and each one hands you back a reference to the vector (chainable, iconic):

• SbVec2b & setValue(const int8_t v[2]) — set from an array of two int8_ts.
• SbVec2b & setValue(int8_t x, int8_t y) — set from two int8_t values.
• SbVec2b & setValue(const SbVec2ub &v) — set from an SbVec2ub.
• SbVec2b & setValue(const SbVec2s &v) — set from an SbVec2s.
• SbVec2b & setValue(const SbVec2i32 &v) — set from an SbVec2i32.
• SbVec2b & setValue(const SbVec2f &v) — set from an SbVec2f.
• SbVec2b & setValue(const SbVec2d &v) — set from an SbVec2d.

getting the values back out, because reading is fundamental:

• const int8_t * getValue(void) const — hands you a pointer to the internal int8_t array.
• void getValue(int8_t &x, int8_t &y) const — writes the two components into your own x and y variables.

element access, lowkey the best part:

• int8_t & operator[](int i) — indexed access, mutable flavor.
• const int8_t & operator[](int i) const — indexed access, but make it const.

math time, no cap:

• int32_t dot(SbVec2b v) const — the dot product with v, returned as an int32_t.
• void negate(void) — flips both components to their negatives, in place.
• SbVec2b & operator*=(int d) — multiply in place by an int.
• SbVec2b & operator*=(double d) — multiply in place by a double.
• SbVec2b & operator/=(int d) — divide in place by an int.
• SbVec2b & operator/=(double d) — divide in place by a double.
• SbVec2b & operator+=(SbVec2b v) — add v in place.
• SbVec2b & operator-=(SbVec2b v) — subtract v in place.
• SbVec2b operator-(void) const — returns the negated copy (the unary minus, bestie).

🧚 Protected Attributes 🧚

• int8_t vec[2] — the actual storage, two bytes doing all the work behind the scenes. protected, so hands off unless you're a subclass. 🙈
